Emission Control System Warranty
United States Emission Control Defects Warranty Statement
The United States Environmental Protection Agency (herein EPA), and Harbor Freight Tools ® (herein HFT) are pleased to
explain the emission control system warranty on your 1995 and later Small Off-Road Engine (herein engine). Within the
United States, new off-road, spark-ignition engines certified for model year 1997 and later, must meet similar standards
set forth by the EPA. HFT must warrant the emission control system on your engine for the periods of time described
below, provided there has been no abuse, neglect or improper maintenance of your engine.
Your emission control system may include parts such as the carburetor or fuel-injection system, and the ignition system.
Also included may be hoses, belts, connectors and other emission-related assemblies.
Where a warrantable condition exists, HFT will repair your engine at no cost to you including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage
The 1995 and later engines are warranted for two (2) years. If any emission-related part on your engine is defective, the
part will be repaired or replaced by HFT.
Harbor Freight Tools Emission Control Defects Warranty Coverage
Engines are warranted for a period of two (2) years relative to emission control parts defects, subject to the provisions set
forth below. If any emission related part on your engine is defective, the part will be repaired or replaced by HFT.
Owner’s Warranty Responsibilities
-
As the engine owner, you are responsible for the performance of the required maintenance listed in your Owner’s
Manual. HFT recommends that you retain all receipts covering maintenance on your engine, but HFT cannot deny
warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
- As the engine owner, you should, however, be aware that HFT may deny you warranty coverage if your engine or a part
has failed due to abuse, neglect, improper maintenance, or unapproved modifications.
- You are responsible for shipping your engine to a HFT warranty station as soon as a problem exists. Contact the HFT
Customer Service department at the number below to make shipping arrangements. The warranty repairs should be
completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact the Harbor Freight Tools
Customer Service Department at 1-800-444-3353.
Harbor Freight Tools Emission Control Defects Warranty Provisions
1 . Length of Coverage
HFT warrants to a first retail purchaser and each subsequent purchaser that the engine is free from defects in materials and workmanship that cause the failure of warranted parts for a period of two (2) years after the date of delivery
to the first retail purchaser.
2 . No Charge Repair or Replacement
Repair or replacement of any warranted part will be performed at no charge to the owner if the work is performed
through a warranty station authorized by HFT. For emissions warranty service, contact the HFT Customer Service
Department at 1-800-444-3353.
3 . Consequential Damages Coverage
Coverage under this warranty shall also extend to the failure of any engine components caused by the failure of any
warranted part while it is still covered under this warranty.
4 . Coverage Exclusions
Warranty claims shall be filed in accordance with the provisions of the HFT warranty policy explained in the box at the
top of the previous page. HFT shall not be liable for any loss of use of the engine, for any alternative usage, for any
damage to goods, loss of time, or inconvenience. Warranty coverage shall also be excluded for any part which fails,
malfunctions, or is damaged due to failure to follow the maintenance
and operating instructions set forth in the Owner’s Manual including, but not limited to:
(a) use of parts which are not authorized by HFT
(b) improper installation, adjustment or repair of the engine or of any warranted part unless performed by an authorized warranty center
(c) failure to follow recommendations on fuel use contained in the Owner’s Manual
(d) improper or inadequate maintenance of any warranted parts
(e) repairs performed outside of the authorized warranty service dealers
(f) alterations by changing, adding to or removing parts from the engine.

Harbor Freight Tools Emission Control Defects Warranty Provisions
5 . Service and Maintenance
Component parts which are not scheduled for replacement as required maintenance or are scheduled only for regular
inspection to the effect of “repair or replace as necessary” are warranted for the warranty period. Any warranted part
which is scheduled for replacement as required maintenance is warranted for the period of time up to the first scheduled replacement point for that part. Any replacement part, provided it is equivalent in durability and performance,
may be used in performance of maintenance or repairs. The owner is responsible for commissioning a qualified
